Hey next time use your calculator, if you can.

Since these problems are using this equation : A(mount) = P(rinciple) * ( 1 + R(ate) ^ {t(ime)} ) we can derive into this immediately.

Q1: 525 (Try it, don't copy, it's not nice ;) ).

Q2: 865.28

Q3: By using logs: 0.0566 years. (I'm not sure on that one...) Sry

Please I need to know if its true or false please lmk!!!​
Papessa [141]

Answer:

False

Step-by-step explanation:

<u>According to the complex conjugate root theorem:</u>

if a complex number is a root of a polynomial, its conjugate is also the root of the polynomial

We are given all the roots of the polynomial and there is only one complex root

Since according to the complex conjugate root theorem, there can be either none or at least 2 complex roots of a polynomial

We can say that this set of roots of a polynomial is incorrect

Equation for given circle. A(4,7) is at center top of circle and B(7,4) is at center right hand side
oee [108]
Note:
The equation for a circle with center at (h,k) and radius r is
(x-h)² + (y-k)² = r²

For the specified circle,
h=4, h=7.

From the diagram shown below, the radius, r, is determined from the Pythagorean Theorem as
r² = 3² + 3² = 18

Therefore the equation for the circle is
(x - 4)² + (y - 7)² = 18

Answer:  (x - 4)² + (y - 7)² = 18
